BUTT-HOOK.

Specification of Letters Patent.

Patented June 1, 1909.

Application filed July 14, 1908. Serial No. 443368.

To all whom it may concern:

Be it known that I, ERNEST WILLIAM SMITH, a citizen of the UnitedStates, and a resident of Myrtle, in the county of Coos and State ofOregon, have made certain new and useful Improvements in Butt Hooks, ofwhich the following is a specification.

My invention relates to hooks and more especially to those hooks thatare employed in connection with log cables or chains for themanipulation and transportation of logs in the process of manufacturinglumber. The hooks attached to the logging cables are commonly known asbutt hooks. The ordinary butt hook consists of a shank having an eye atone end and a bent portion at the other end which constitutes the hookmember. A short piece of wire cable is fastened to the hook and in usethe cable is passed around the log and the hook is inserted into an eyespliced in the other end of the cable. It often ha )pens that in thevarious movements of the 0g the cable becomes unfastened owing to thefact that the eye has slipped off the point of the hook. Various meanshave been devised for preventing this, and one object of my invention isto provide a device in which there is no possibility of the point' ofthe hook heing disengaged from the eye. To this end, I have provided alocking member on the hook which looks the eye so that it cannot bewithdrawn or disengaged from the hook itself unless the locking memberis moved. At the same time the locking member can be easily adjusted topermit the withdrawal of the cable.

My invention is illustrated in the accompanying drawings in which Figure1 is a side view of my improved butt hook, showing the locking member ina retracted position; Fig. 2 is a similar view showing the lockingmember in its forward locking position; Fig. 3 is a plan view of thehook and locking member.

Referring now to Fig. l, A denotes in general a hook having a loop B,adapted to per mit the entrance of an eye of the logging cable. The hookterminates in a oint C which is immediately opposite the sioulder D onthe shank of the hook, the opening between these two members being justlarge enough to admit freely the eye of the cable. The shank ofthe hookhas a threaded portion E and disposed on the threaded portion is ahexagonal nut F, having threads arranged to cooperate with the threadsof the part E, thereby permitting the nut to be moved longitudinally ofthe shank into close engagement with the shoulder D.

When the nut F is moved into engagement with the shoulder D the openingbetween the end of the nut and the point C is too small to permitdisengagement of the eye of the cable. If it is desirable the nut may bebrought near enough so that the opening will be entirely closed.

The shank of the hook terminates in a flattened portion G which is madeby spreading the cylindrical shank thereby forming a stop member whichprevents the nut F from coming off. The flattened end portion G isperforated to form an eye H to which the end of the cable may beattached.

In the use of the hook the cable is placed around the log, in the manneralready described, with the nut in the position indicated in Fig. 1, thecable eye inserted in the loop of the hook and the nut is then turneduntil it closes the opening between the moirbers C and D. I prefer tohave the nut of a hexagonal shape, although obviously it may have anyother shape or may be milled on its outer circumference. In thepreferred sha e however, the nut may be screwed up tight y against theshoulder D by means of a wrench or other tool so that there will be nopossibility of its coming loose and retracting far enough to permit thedisengagement of the eye of the cable.

I am aware that there are certain forms of snap hooks which have aspring actuated locking member extending between the shank and the ointof the hook, but one trouble with a evice of this kind is that if thelink is given a sudden blow in the reverse direction, that is toward thepoint of the hook, the light spring actuated member, or the point of thehook itself, as the case may be, is liable to be broken off and thecable to be disengaged.

My invention on the other hand, provides a locking member which in itslocking position serves to receive the force of a reverse thrust and isof suflicient thickness as to prevent a breakage of the kind justreferred to.

I claim 1. A butt hook, comprisin a threaded cylindrical shank, anenlarged flattened head at one end of said shank provided with an eye, ahook member at the other end of said I from said shoulder to provideshank provided with a shoulder immediately adjacent to the threadedportion of said shank and terminating in a point opposite said shoulder,and a threaded nut disposed on said threaded-shank and arranged to bemoved longitudinally therealong, said nut being restricted in itsmovement in one direction by the enlarged head and being adapted torestrict the opening between the point of the h ook and said shoulderwhen in engagement with said shoulder.

2. A butt hook, comprising a threaded shank having an enlarged flattenedend portion provided With an eye, a nut disposed on said threaded shankand arranged for movement therealong, a hook member at one end of saidshank having a shoulder andterininating in a point, said point beingspaced apart an opening into the loop of the hook.

A butt hook eonqnising a threaded shank terminating at one end in anenlarged head, a hook member at the other end of said shank bent to forma loop with a narrow opening, a stop, and a nut on said threaded shankarranged to be moved into engagement with said step and to restriet theopen ing in the loop of said hook 4. A butt hook comprising a threadialshank and an integral hook member, and neans adjustable along said shankfor locking said hook.
